Alkaloids from the sea sponges as stimulants of growth, development and productivity of agricultural plants

Abstract

The natural world of the Far East Russia has great potential for the detection and isolation of biologically active compounds that can increase productivity of agricultural plants in the zone of risky agriculture. Growth regulating activity of metabolites of marine organisms -alkaloids were studied. Damirone B (1), debromohymenialdisine (2), and dibromoagelaspongin (3) were tested in field conditions as growth stimulants of barley (Hordeum vulgare L.), wheat (Triticum aestivum L.) and common buckwheat (Fagopyrum esculentum Moench). It was shown that the stimulatory effects depend on the chemical structure of the alkaloids and the plant species. Compounds 1, 2, and 3 at different concentrations, stimulate growth and productivity of barley, wheat and buckwheat. Their introduction into practice will increase plant productivity, and hence the profitability of crop production.
